Product overview
The QIHEHUI G30 combines a tethered box, tether cable and onboard power supply. The box accepts 380VAC ±10% at 50Hz and provides 200--1000VDC, with a factory setting of 1000VDC. Its rated power is 30KW, with a 40KW peak. Measuring 690/506/302mm and weighing 45Kg, it incorporates a touchscreen for voltage, current, power, temperature, cable status and working status. Standard cable lengths are 110/220m, with custom lengths available upon request. The 5.8mm cable weighs 38g/m and carries a specified current of 25A.
The onboard power supply requires 800--1000VDC input and provides 50/59/76VDC outputs corresponding to 12S/14S/18S, with a specified power of 24KW. Its 388/295/54.5mm dimensions and 5.3Kg weight define the onboard space and mass allocation. External leads provide the electrical interface, while pre-drilled M3 threaded holes provide mounting points; custom interfaces and mounting options are available upon request. The specified takeoff weight range is 90--130Kg. Cable construction combines a silver-plated steel wire conductor, fluoroplastic and Teflon insulation, and a Kevlar reinforced braided layer.
